3.6 Respiratory System Flashcards
The respiratory system
Supplies the body with oxygen and removes carbon dioxide in a two-step process including inspiration and expiration of air from the lungs
Nose
Organ of smell, Air is filtered moistened and warmed before it travels to the lungs
Mouth
Opening through which air food and beverages enter the body, beginning of the alimentary canal.
Pharynx
Throat, the crossroads of the nose, mouth, voice box, and esophagus. Food continues down the esophagus while air passes through the larynx to the trachea
Trachea
The windpipe, divides into two tubelike structures (the right and left bronchi) that extend into the lungs
Lungs
Main organs of the respiratory system whose function is transporting oxygen into the blood and removing carbon dioxide from the blood
 Bronchi
The main passageway for air to travel from the trachea to the lungs
Physical differences between the right and left lung?
The right lung consists of three lobes while the left lung consists of two lobes to allow space for the heart
Function of the diaphragm?
A muscle located below the lungs, contraction allows the chest cavity to expand and allow more space for air. During expiration, the diaphragm relaxes and air is forced out of the lungs.
Thoracotomy
Making an opening into the thoracic cavity to give surgeons access to the lungs and heart
Thoracoscopy
Viewing the thoracic cavity with an endoscope for diagnosis or treatment
Pneumonectomy
Removal of a lung
Tracheotomy
Making an incision into the trachea
Lobectomy
Removal of a lobe of an organ usually referring to the brain the lungs or the liver
Laryngectomy
Removal of the larynx/voice box
